类 HiddenFileFilter

java.lang.Object

org.apache.commons.io.filefilter.AbstractFileFilter

org.apache.commons.io.filefilter.HiddenFileFilter

所有已实现的接口:

FileFilter, FilenameFilter, Serializable, IOFileFilter

public class HiddenFileFilter
extends AbstractFileFilter
implements Serializable

This filter accepts Files that are hidden.

Example, showing how to print out a list of the current directory's hidden files:

 File dir = new File(".");
 String[] files = dir.list( HiddenFileFilter.HIDDEN );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
 }
 

Example, showing how to print out a list of the current directory's visible (i.e. not hidden) files:

 File dir = new File(".");
 String[] files = dir.list( HiddenFileFilter.VISIBLE );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
 }
